Would it be possible to come up with some kind of motivation for people to complete the escape storyline? Perhaps an extra feat point (or a few) if you rejoin the same server, and make it cumulative, so that people have a reason to do it multiple times. I think it would add an extra tactical consideration for clans who wouldn’t want all of their power players to go at the same time. If you added a nerf to the yellow lotus pot to make bonus feat points more valuable, I think this would add an additional motivation for playing.
Or maybe not, just spitballing here.
